IGELESS REFRIGERATOR.

Application filed .Tuly 21, 1924. Serial N0.`727,360.

T0 all whom t may] concern:

Be it known that I, Emst-IA I-I. a citizen of the United States,residing at Richmond, in the county of lWayne and State of Indiana, haveinvented certain new and useful Improvements in an Iceless Refrigerator,of which the following is a specification, reference being had thereinto the accompanyin drawing.

My invention rela-tes to improvements in celess, portable refrigerators,commonly known as window refrigerators, beingl adaptedto be placed inwindow openings in houses, say the window of a pantry or kitchen.

The essential object of my invention, in order to make an icclessrefrigerator, is the provision for a water supply near the top of thecompartment, an absorbent basin at or near the bottom and devicespreferably in the nature of wicks by which water from said supply may beslowly and constantly conveyed to such basin where it is absorbed, buttends to evaporate, with the resultant Incidentally, the water supplyalso tends to evaporate and in that way acts to aid in lowering thetemperature within the compartment.

A further object of the invention consists SCOTT,

in 'certain structural features, namely, the

special manner hereinafter stated of forming or striking up thedifferent plates `which are to constitute the walls of the article, suchas the bottom, top, back and ends. whereby the cost of production willberednced and durability of the article obtained, and whereby arefrigerator may be provided which can be shipped and stored in aknocked-down condition and readily assembled by inexperienced persons.

In the accompanying drawings:

y In these drawings, I have shown my improved refrigerator as having abase l comprised in the present instance of portions extendingdownwardly from a bottom 2 and reenforced by end walls 3 and back wallt, as will hereinafter appear. The top wall 5 for the refrigeratorcompartment is preferably inclined rearwardly and is provided with anopening adapted to be closed by a cap 6 having threads which engage withthreads on a collar 7. A door 8 hinged to one of the end members 3completes the enclosing of the refrigerator compartment. A member in theform of a basin having a bottom 9 and sides 9"L which may be made of anysuitable absorbent material, as coment, soapstone, or unglazed.earthenwarm is supported by the bottom 2` by directly placing the samethereon or in any other suitable manner. A container l0 for water isconveniently mounted near the top of the compartment and the desiredsupply of water is maintained through the opening in the top of thecasing referred to above. Means for conveying' water slowly butconstantly from the container l() to the absorbent basin 9, in thepresent instance wicks 11, are provided and louvres 12 in the end wallsl3 permit air drafts through the refrigerator, whereby a system ofevaporation will be maintained and the temperature of the compartmentkept low enough for refrigerating purposes. r y v In case the basin 9should absorb more water than'can be thrown olf by evaporation, thebottom 2 is provided with a rearwardly inclined depressed portion orgroove 1 3. which will receive any drippings from the baSn and fromwhich they may be readily discharged, as through an opening 14. A screen15 is secured to that portion of the end Walls having the louvres toprevent the entrance Vinto the compartment of flies or other insects.

Trays or shelves may be arranged Within the refrigerator to hold theviands it is desired to place therein and in Figure 1 I have shownbrackets 16 to supportv such trays.

Referring now to certain structural features of my invention, such asthe manner of striking up or forming the Walls of the refrigeratorcompartment, as the bottom, top, back and ends, it will be seen fromFigures 3 to 6 inclusive, that the blanks have been formed in such a Waythat the parts may be shipped and stored in a .knocked down conditionand readily assembled by inexperienced operators and that the resultingstructure Will be strong and durable as Well as inexpensive.

Referring first to the illustration of the blank for the top 5, itcomprises a substantially rectangular main portion having extensions onits margins, the extensions on the end and rear margins adapted to befolded along the dottedV lines 16 back substantially parallel'to themain portion to form grooves, as shown in- Figures 3A and 3G.v Openings117 the extensions and o-penings 18 in the main portion register withone another for the purpose hereinafter set'forth. The front margin ofthe blank for the top 5 is folded along the dotted'l lines 19 soY thatthe portion 201 Will bev fl-usli- With the in ain portion and thenfolded along the dotted line 21 so that the portion 22 Will be at asubstantially right angleto the niain portion and` form a flange withwhich the upper part of the door Wil-l contact, as shown in Figure 3B.

I Will now refer to the blank for the end Wall 3, the main portion ofWhich has its top slightly inclined from the front to the rear and hasetxensions along its margins. The extension on the top margin is adaptedto be folded along the dotted line 23 at an angle to the mai-n portionto form a tongue 24 Which enters one of the; grooves formed in the blankfor the top, as shown in Figures 3C and 4^. VAn1 openingfQ in the tongue24 registers Wit-h the openings 17 and 13 in the groove sections at theends-of the blank for the. top and receiveV fastening means, as shown at26, for securing said partstogether. The extensions; on the rear andbottom margins 'of' theV main portion of the blank. for the en'd 3arebent alongthe dotted lines 27 back4 substantially parallel to themain portion; of" the; end blank to. form grooves, ais-'shown in Figures4j?I3 v and 4P' and have openings 23' which Will register with openings.295th: the assembly offthe device; The eartension.'onw the: "frontmarginofthe blank for the end' 3 is folded at substantially a rightangle to the main portion, as shown in Figure 4C, to form a flange 30for contact with the door 8. It Will be noted that the end blanks alsohave portions stampedV to form the louvres 12 hereinafter referred to.

In Figure 5 I have shown the blank for forming the back of therefrigerator compartment substantially rectangular and having extensionsat its margins, the extensions at the end margins adapted to be bentalong the dotted lines 31 to form tongues 32 extending at substantiallyright angles to the main portion 4, as shown in Figure 5B. These tonguesextend into the grooves formed by the rear margins of the end Walls 3and are provided with openings 33 which register with the openings 23and 29 to receive fastening devices 26 to secure the parts in positionrelatively to one another. The extension at the rear margin of the blankfor the back Wall 4 is also bent at right angles to the main portion ofthe blank and along the dotted line 34 to form a tongue 35 which entersthe groove formed at the` rear of the top blank 5 and is secured inplaceY by fastening means 26 passing through the openings 17 and 13 insaid top blank 5 and an opening 36 in the tongue 35, as shown `in Figure5A. The extension at the front margin of the blank for the back 4 isbent upon the dotted line 37 back substantially parallel with the mainportion of the blank to forin a groove, as shown in Figure 50. Openings100 38 and 39register With one another and with a corresponding openingin another blank in the assembly of the device. y

In Figure 6 Will be seen blank for forniing the bottom Wall 2 having adepressed 105 portion 13 inclined from front to rear with Y an opening14 liereinbefore referred to. The main portion of the blank issubstantially rectangular in sli-ape and has extensions at its marginseach adapted to be bent down- 110 Wardly at right angles to the mainportion and along dotted lines 40. The bent portions at the endmarginsforni tongues 41 which enter grooves formed by the end Walls 3,as shown in Figure 6B, While the bent 115 portion at the rearmarginpforms a tongue 43 which enters the groove formed bythe blank forthe back Wall 4 as shown in Figure 6A. Each tongue 4 1` is provided withan opening 44 and thetongue 43 has open- 12W ings 45 similar to theopenings referred to in the other blanks and performing the samefunction. The bent portion at the front of the' blank for the bottoni 2'serves as a flange 46 for contact with the door, as 125 shown in Figure6C.

Thus it Wil be seen that with'the: blanks for the several, Walls sofashioned they Vwill have an interittin-g relation which will, permit ofready assembly' by?v inexperienced per- 130 sons, thereby providing adevice Which may be shipped and stored in a knocked down condition. Theordinary refrigerator is not only bulky and the freight rate highconsidering the Weight but requires considerable storage space. By myimproved knocked down refrigerator which is light in Weight, While atthe same time strong and durable., the shipping expense is materiallyreduced and the storing thereof greatly facilitated.

It will be understood that I desire to comprehend Within my inventionsuch modifications as may be necessary to adapt it to varyingconditions.

Having thus fully described my invention, what I claim as new and desireto secure by Let-ters Patent, is

l. In an iceless refrigerator, the combination with a compartment formedof e11- closing Walls, some of said Walls having louvres for theadmission of air drafts, of

a Water container near the top, an absorbent basin near the bottom, andWicks extendin from the container to the basin and adapted to deliverattenuated supplies of Water to the basin, such Water supply and basinbeing adapted to give olf evaporation.

2. In an celess refrigerator, the combination with a compartment formedof enclosing' Walls, some of said Walls having louvres for the admissionof air drafts, of a- Water container near the top, means for `sua lfinfrWater to said container an absorbent basin near the bottom of thecompartment, water conveying means extending from the container to thebasin and adapted to deliver attenuated supplies of Water to the basin,and means for receiving any drippings from said basin.

In testimony whereof I affix my signature.
